To all whom it may concern.-

Be it known that I, VICTOR POPP, of the city of Paris, France, haveinvented a new and useful Device for Automatically \Vinding upGounter-VVeights by Means of Fluid,Gas,or other Pressure, of which thefollowing is a full, clear, and exact description.

This invention consists of a system of automatically winding upcounter-weights for transmitting or accumulating power, based 011 theemployment of a fluid, liquid, vapor, or gas under a constant orvariable pressure acting on the elements, which I shall describe fartheron, and which I have shown on the appended drawings, but solely as anillustration.

In the drawings, Figure 1 shows a complete View of my system ofautomatically winding up counter-weights as applied to the motive partof a Hughes telegraph, the upper wheel being the driving-wheel of themechanism of said Hughes telegraph. Fig. 2 is a detail drawing, showinga front elevation, in partial section, of the devices for distributingthe compressed fluid.

In the figures the same letters refer to the same parts.

My apparatus comprises two principal parts: first, a cylinder, A, inwhich works a piston, B, which is acted upon on one side only by thepressure of the fluid, the other side being open to the atmosphere;second, a three-way cock lt, for distributing the compressed fluid tothe cylinderA and for exhausting the same fluid when the end of it hasacted on the piston B. The handle of the cock is furnished with a hollowcrossbar, T, which is filled to about one-third of its interior volumewith mercury. This crossbar opens or closes the cock at the desiredmoment. This being premised, the operation of the apparatus is asfollows:

The weight P, acting on the elements which it has to set in motion,descends under the in fluence of its own weight. The two parts 0 C ofthe chain descend. with it, while the parts 1) D of the same chainascend, lifting the counter-weight E, the sheave F, and the block G,fixed onthat sheave. This block G, in the form of an extended ring,inoloses one of the ends of the cross-bar T. Vhen the weight P hasnearly arrived at the ends of its course, the block G in its upwardmovement lifts the crossbar T. The mercury inside is gradually displacedby the lifting of the cross-bar, and

when the latter has reached a point a little beyond the horizontal it(the cross-bar) is operated by the weight of the mercury, which has allgone over to the other end of the cross bar. At this momentthe cock isopened to its whole extent. The fluid under pressure, supplied throughthe pipe M, connecting with a receiver for compressed air or othercompressed fluid,water, steam, &c., or with a compressing pump, passesthrough the pipe N into the cyl inder A and acts on the piston B,forcing it to the other end of the cylinder. By means of the rod H and achain, I, the motion of the piston is transmitted to a disk, 0, keyed onthe shaft which carries the return-sheave of the parts 0 and D of thechain supporting the weight P. The weight is thus brought back (woundup) into its normal position; but while the weight P is being wound upthe block G descends, and when the weight 1? is at the end of its coursepulls the cross-bar T of the cock back in the opposite direction to itsfirst movement. The mercury again exerts its tilting action and placesthe cross-bar in the position shown in dotted lines on the drawings,Fig. 2. At this moment theinlet-opening of the cock is closed and theescape-pipe L is put in communication with the cylinder A, so as toafford an outlet for the fluid after it has acted on the piston. I

When the weight P has gone down again, the same operations are repeated,so that the winding up of the weight takes place automatically andalternately.

V is a spring serving to bring back the piston to the front end of thecylinder. This spring may be of any shape, and may be replaced either bythe admission of the fluid to the other side of the piston or by theemploymentof another cylinder with its piston.

The winding up of the weight by means of electricity may be effected bychanging the cock B into a commutator, which, according to thedifl'erent positions it may take, Fig. 2, would establish or break anelectrical circuit.

I claim 1. The combination of the cylinder provided with a piston,conduits N and L, the threeway cock having the hollow cross-bar, the

, block G, the wheel or disk F, the chain 0 D, the pulleys over whichsaid chain works, and 5 the counter-weight P, substantially as and forthe purpose set forth.

2. The cock R, in combination with a hollow cross-bar, T, filled aboutone-third with a heavyliquid, the tilting movement of this crossro baroperating this cock, as described and illus trated.

3. The combination of the cylinder A, provided with a piston, B,conduits Nand L, the three-way cock B, having a hollow crossbar,

T, the block G, the wheel or disk F, the chain 1 G D, the counter-WeightP, a number of pulleys or wheels, and a spring connected to the pistonthrough its piston-rod and a chain passed over one of\said pulleys,substantially as and for the purpose set forth. 20
